BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to eyeglasses and a method for use thereof, and more specifically to customizable eyeglasses with adjustable lenses.

2. Description of the Related Art

Existing techniques for making and prescribing eyeglasses is costly and time consuming. Eyeglass manufacturing takes anywhere from ten minutes to an hour with a standard machine called a Lens Edger, and that machine can cost anywhere from $25,000 to over $100,000. The machine requires electricity and a reliable facility to operate in. This limits its usefulness in situations such as in third-world countries or remote locations.

What is needed is an affordable, highly-customizable, and easily adjustable eyeglass system which can be used in any situation, and is especially useful for remote and poor locales.

Heretofore there has not been available a system or method for an eyeglass customization system with the advantages and features of the present invention.

BRIEF SUMMARY OF THE INVENTION

The present invention generally provides a customizable eyeglass system for use in any remote situation, and which is ideal for use in third-world countries or areas where electrical power and typical machinery for manufacturing eyeglasses is lacking.

The system generally includes several parts which can easily be fit together from a kit of standard parts to form customized eyeglasses for a patient. The system includes a frame with receivers for the temples to connect into and lock into place. A pair of customizable lenses is connected to the front of the frame. The lenses can be rotated to dial in the correct prescription for the patient and then locked into place as well. If adjustments need to be made, the patient can easily unlock the lenses, rotate them to a proper orientation for proper sight, and then lock the lenses into place again.

Said terminology will include the words specifically mentioned, derivatives thereof and words of similar meaning.

II. Preferred Embodiment Eyeglass System 2

As shown in the figures, the preferred embodiment eyeglass system 2 generally includes a frame element 4, two temples 8, and two lens assemblies 6. The frame generally includes two circular lens-receivers 10 joined together by a bridge 12. Each lens-receiver 10 includes a nose piece 22 and a temple receiver 14. FIGS. 2 and 3 show that the lens-receivers 10 each have a first lens 23, and the lens assembly 6 has a second lens 24. The first lens 23 is typically a sphere lens, which is prescribed to correct distance vision of a patient, whereas the second lens 24 is intended to correct astigmatism.

Each lens assembly 6 connects to the lens-receiver 10 by locking a rim 20 running around the inside of the lens body 26 into locking grooves 16 which are part of the lens receivers 10. The grooves 16 allow the lens assemblies 6 to freely rotate along the rim 20. The lens bodies 26 each house the second lens 24, which focuses depending on the rotation of the lens assembly 6, thereby correcting a user's vision. Each lens assembly 6 also includes a tab 18 which makes it easy for the user or the user's eye doctor to rotate the lens assembly. The tab 18 then can be depressed or slid or otherwise adjusted such that it locks the lens assembly 6 into place, preventing further rotation until the tab 18 is unlocked. The second lens 24 has approximately 180 different points of correction addressing any users that requires astigmatism correction, such that while rotating the lens, the user will see their vision change until it is clear, at which point the user will stop rotating the lens assembly 6. The two lenses 23, 24 combine to fully correct a user's vision.

In this way, anyone be it an eye care professional or any average citizen can quickly assemble a customized pair of corrective eyeglasses in any location in the world, including very remote or very poor locations. By combining pre-constructed pieces, including the temples 8, frame 4, and lens assemblies 6, the eyeglasses can be customized to fit any users' face and adjusted to correct any users' vision.

In a method of practice, a user or eye-doctor/optometrist will prescribe the user a first lens 23 prescription. These will also be available in color-coded grades to help with illiterate persons when choosing replacement lenses and frames for damaged or lost eyeglasses. Once the frame 4 is fit with the first lens 23, the second lens 24, housed in the lens assembly 6, shall be placed on top. Once installed, the user can dial in the second lens 24 by rotating the lens assembly 6 until their astigmatism is corrected. If the tab 18 can be activated to lock the lens assembly 6 into place, the user may do so at that time.

Each lens 23, 24 in the preferred embodiment of the present invention includes 2 sets of lenses that have 100% ultra-violet light (“UV”) protection as well as a 15% tint coating. This triple UV filtering action can help to prevent multiple eye and skin diseases, including Pterygia, Pinguecula, cataracts, retinal damage including macular degeneration, and cancers such as melanoma or eyelid skin cancers including basal cell carcinoma and squamous cell carcinoma. The present invention is intended to prevent all such diseases as a result of UV damage. Approximately more than half of all malignant melanoma is directly correlated to UV radiation.

The first set of lenses 24 have a 100% UV protective coating applied to a surface of that lens. A 15% gray tint is also applied to that lens surface which filters out harmful radiation as well as harmful UV rays. The 15% tint also reduces blue light effects which can damage vision and result in loss of sight.

The second set of lenses 23 provides a third level of protection. They have a protective 100% UV coating similar to that applied to the first set of lenses 24. In the event of prolonged exposure to high levels of UV light, this third level of protection will protect against any rays that somehow pass through the first set of lenses 24, or rays that somehow reflect around the first lenses.

FIG. 3 shows this feature in detail. Light 32 is emitted from the sun 30 in several spectrums, including UV-A, UV-B, and the safe spectrum. As UV rays pass through the first set of lenses 24, the harmful UV-A and UV-B rays are removed, and light 33 passes along to the second set of lenses 23 only in the safe spectrum. The second set of lenses 23 also filters out any harmful UV-A and UV-B rays which may have passed around the edges of the first set of lenses 24, and only the safe spectrum light 33 is allowed to pass on to the eyes 34 of the user.

It should be noted that, while the example above shows round glasses frames and lens assemblies, it is possible to use the present invention in any shape of frame and lens. In other embodiments, a portion of the second lens may rotate within an otherwise differently shaped lens body, thereby creating the same result as described above.
